In the definitions of the radicals of formula I alkyl is understood to encompass straight-chain and branched alkyl groups, with branched-chain and lower alkyl being preferred. For example alkyl is methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tertiary butyl or secondary butyl. Alkoxy for example encompasses methoxy, ethoxy, n-propoxy, isopropoxy, n-butyloxy, isobutyloxy, tertiary butyloxy or secondary butyloxy. Halogen designates fluorine, chlorine, bromine and iodine, with fluorine and chlorine being preferred. Haloalkyl designates straight chain or branched alkyl groups which are mono- to perhalogenated with straight-chain lower alkyl being the preferred alkyl and with fluorine and chlorine being preferred halogens. Examples are trifluoromethyl, difluoromethyl, 2,2,2-trifluoroethyl or 2,2,3,3,3-pentafluoropropyl. Aryl stands for aromatic hydrocarbon radicals, for example phenyl, naphthyl or anthracenyl, with phenyl being preferred. The aryl radical may obtionally be further substituted. Aryloxy designates an aryl radical being bounded through an oxygen atom. Examples are phenoxy, naphthyloxy or anthracenyloxy. The aryloxy radical may optionally be further substituted at the aryl part. Alkenyloxy designates for example allyloxy, 2-butenyloxy, 3-butenyloxy, 2-pentenyloxy, 2-methallyloxy, 3-pentenyloxy, 4-pentenyloxy, 2-methyl-2-butenyloxy, 3-methyl-2-butenyloxy, or 3-methyl-3-butenyloxy.

Arylalkoxy is for example benzyloxy, 2-phenylethoxy or 1-phenylethoxy or 3-phenylpropoxy. The arylalkoxy may optionally be further substituted at the aryl part. The alkylene bridge formed by R⁴ and R⁵ together may be straight chain or branched. Examples are --(CH₂)₃ --, --(CH₂)₄ --, --(CH₂)₅ --, or --CH₂ --CH₂ --CH(CH₃)--CH₂ --. The alkylene chain designated by E is for example --CH₂ --, --CH₂ --CH₂ --, --C(CH₃)₂ --, or --CH(CH₃)--.

The double bond in formula I and II may be in E or Z-form. In this document the E and Z-forms are identified where meant specifically. In all other cases mixtures of the two isomers are intended. Dependent on the synthesis conditions used, the E- and Z-isomers are produced in different ratios from 100% E/0% Z to about 30% E/70% Z.

Where E an Z isomers are obtained during synthesis they may be separated by known techniques, such as crystallisation, chromatography or distillation.

Compounds of formula I are obtained by O-methylation of a compound of formula II ##STR5## wherein R¹, R², R³, R⁴, R⁵ and X are as defined above, resulting in compounds of subformula Ia ##STR6## wherein X, R¹, R², R³, R⁴, R⁵ and X are as defined above, and optionally converting the compounds of formula Ia into the compounds of subformula Ib ##STR7## wherein R¹, R², R³, R⁴, R⁵ and X are as defined above and Y' is NH₂, NHCH₃ or N(CH₃)₂, by an amidation reaction with NH₃, NH₂ CH₃ or NH(CH₃)₂, respectively.

The O-methylation can be carried out in a manner known per se for the preparation of 3-methoxyacrylates employing conventional methylation agents. Examples of suitable methylation agents include methyl iodide and dimethylsulfate. The O-methylation is conveniently carried out in the presence of a base.

The reaction temperature will conveniently lie in the range of from 0° C. to the boiling point of the reaction mixture, e.g. at about ambient temperature. Inert solvents may be used where desired. Examples of suitable bases include alkaline metal hydrides such as sodium hydride, alkaline methyl alcoholates such as sodium methylate, alkaline metal carbonate or sodium hydrogen carbonate. Examples of suitable inert solvents include aromatic hydrocarbons such as benzene and toluene; ethers such as diethyl ether, tetrahydrofuran and 1,2-dimethoxyethane; polar solvents such as dimethylformamide, dimethyl sulfoxide, water, alcohols such as methanol; acetone or a mixture comprising two or more of them. The desired end-product is isolated and purified according to known techniques, for example by evaporation of solvent, chromatography and crystallisation. The compounds of formula I are basic in nature. They may form salts with sufficiently strong acids such as HCl and HBr.

The optional conversion of the compounds of subgroups Ia to subgroups Ib is a transamidation process which is carried out under the reaction conditions usually employed for this type of amidation reaction. Preferably, the ester compounds of formula Ia (Y is OCH₃) are treated with the amine component (ammonia, methylamine or dimethylamine). Advantageously, the reaction is carried out in an inert polar solvent like dimethylformamide, or in an excess of the amine. The reaction temperature is not critical, but will preferably be between 0° C. and +60° C., e.g. at room temperature.

The compounds of formula II wherein X is CH may be obtained by reaction of compounds of formula III ##STR8## wherein R¹, R², R³, R⁴ and R⁵ are as defined above with a formylating agent, e.g. N,N-diformylmethylamine, or methyl formate in the presence of a base.

This reaction is essentially a Claisen reaction and may be carried out under the conditions known for such reaction. The reaction (III→II) may be carried out in an inert solvent. Examples of suitable solvents are as described for the O-methylation of the compounds of formula (II). Examples of suitable bases are such typically used for a Claisen reaction such as alkaline metal alcoholates, e.g. sodium methylate; alkaline metal hydrides, e.g. sodium hydride; and lithium amides or sodium amides, e.g. lithium diethylamide. The reaction temperature may vary within wide ranges, e.g. from 0° C. to the boiling point of the reaction mixture and is preferably at or near ambient temperature.

The compounds of formula II wherein X is N may be obtained by reacting a compound of formula III with an alkyl nitrite in the presence of a base, optionally in the presence of an inert solvent. In a variant of this process the compounds of formula II wherein X is N may also be obtained by reacting a compound of formula III with an alkyl nitrite in the presence of hydrochloric acid, optionally in an inert solvent. The reaction temperature will conveniently lie in the range of from -40° C. to +30° C. e.g. at about 31 20° C. to 0° C. Inert solvents may be used where desired. Examples of suitable bases include alkaline metal hydroxides such as sodium hydroxide, alkaline metal hydrides such as sodium hydride and alkaline metal alcoholates such as sodium methylate. Examples of suitable inert solvents include aromatic hydrocarbons such as benzene and toluene; ethers such as diethyl ether, tetrahydrofuran and 1,2-dimethoxyethane; polar solvents such as dimethylformamide, dimethyl sulfoxide, water, alcohols such as methanol; acetone or a mixture comprising two or more of them.

In a variant of the two-step process (III→II→I), the compounds of formula I may be obtained by a single-vessel reaction from compounds of formula III, without isolation and purification of the intermediate compounds of formula II.

The acetic acid esters of formula III may be obtained from compounds of formula IVa when R₁ is C₁₋₄ alkoxy ##STR9## wherein R¹ is C₁₋₄ alkoxy and R⁵ is as defined above, by reacting it with a phenol of formula V ##STR10## wherein R², R³ and R⁴ are as defined above in the presence of a base and an inert solvent. Suitable bases and solvents are as for (II→I), or from compounds of formula IVb when R₁ is --NR₈ R₉ ##STR11## wherein R², R³, R⁴ and R⁵ are as defined above, by reacting it with an amine HNR₈ R₉, wherein R₈ and R₉ are as defined above.

The compounds of formula IVa may be obtained by reacting dichloropyrimidinyl acetic ester of formula VI ##STR12## wherein R⁵ is as defined above, with a compound of the formula VII

    H--R.sup.1                                                 (VII)

wherein R¹ is as defined above, in the presence of a base and an inert solvent.

The compounds of formula IVb may be obtained by reacting dichloropyrimidinyl acetic ester of formula VI with a phenol of formula V in the presence of a base and an inert solvent.

The reaction temperature is with advantage kept below +20° C. with cooling. Suitable bases are for example sodium methylate, for R¹ being methoxy, and tertiary amines, e.g. triethylamine, for R¹ being NR⁸ R⁹.

The compounds of formula VI may be obtained by reacting a compound of formula VIII ##STR13## wherein R⁵ is as defined above, with a chlorinating agent, preferably in the presence of a base.

The reaction is preferably carried out at elevated temperatures (up to +130° C.). Suitable chlorinating agents are POCl₃, COCl₂, SOCl₂ or PCl₅. Suitable bases are tertiary amines, such as N,N-diethylaniline.

The compounds of formula VIII may be obtained by reacting a compound of formula IX ##STR14## with formamidine or acetamidine in the presence of a base.

The reaction is preferably carried out with cooling at a temperature between -20° C. and +20° C. in an inert solvent. A suitable solvent is methanol. The suitable base is sodium methylate.

The intermediates of formulae II, III, IVa, IVb, VI and VIII have especially been developed for the synthesis of the compounds of formula I. They therefore also constitute a part of present invention.

Where derivatisation of the compounds of formula I into other compounds of formula I is desired, e.g. by transforming certain radicals into other radicals, which also are within the definition of formula I, such derivatisation may be effected by chemical methods known per se, e.g. acetalisation, amidation, transesterification and the like.

The starting materials of formulae V, VII and IX are known, or can be obtained according to methods known per se, or by methods analogous to the methods used for known compounds.

The intermediates of formula III wherein R² is --C(CH₃)═N--O--R⁶ or ##STR15## may suitably be prepared from the corresponding carbonyl compound of formula X ##STR16## wherein R¹, R³, R⁴, R⁵ and R⁷ are as defined above, with a suitable acetalising agent of formula XI ##STR17## wherein E is as defined above, or with an oxime forming agent of formula XII

    H.sub.2 N--O--R.sup.6                                      (XII)

wherein R⁶ is as defined above.

The compounds of formula X have especially been prepared for the synthesis of the compounds of formula I. They are thus a part of present invention.

Many of the compounds of formula I have an excellent plant tolerance and a systemic action. The compounds of the invention are therefore indicated for treatment of plant, seeds and soil to combat phytopathogenic fungi, e.g. Basidiomycetes of the order Uredinales (rusts) such as Puccinia spp, Hemileia spp, Uromyces spp; and Ascomycetes of the order Erysiphales (powdery mildew) such as Erysiphe ssp, Podosphaera spp, Uncinula spp, Sphaerotheca spp; as well as Cochliobolus; Pyrenophora spp; Venturia spp; Mycosphaerella spp; Leptosphaeria; Deuteromycetes such as Pyricularia, Pellicularia (Corticium), Botrytis; and Oomycetes such as Phytophthora spp, Plasmopara spp.

The compounds of formula I are particularly effective against powdery mildew and rust, Pyrenophora and Leptosphaeria fungi, in particular against pathogens of monocotyledonous plants such as cereals, including wheat and barley.

The amount of compound of the invention to be applied, will depend on various factors such as the compound employed, the subject of the treatment (plant, soil, seed), the type of treatment (e.g. spraying, dusting, seed dressing), the purpose of the treatment (prophylactic or therapeutic), the type of fungi to be treated and the application time.

In general, satisfactory results are obtained, if the compounds of the invention are applied in an amount of from about 0.01 to 1.0, preferably about 0.05 to 0.5 kg/ha, in the case of a plant or soil treatment; e.g. 0.05 to 0.5 kg of active ingredient (a.i.) per hl in field crops such as cereals, or concentrations of 5 to 50 g of a.i. per ha in crops such as fruits, vineyards and vegetables (at an application volume of from 300 to 1000 l/ha--depending on the size or leaf volume of the crop--which is equivalent to an application rate of approximately 15 to 500 g/ha). The treatment can, if desired, be repeated, e.g. at intervals of 8 to 30 days.

Where the compounds of the invention are used for seed treatment, satisfactory results are in general obtained, if the compounds are used in an amount of from about 0.05 to 0.5, preferably about 0.1 to 0.3 g/kg seeds.

The term soil as used herein is intended to embrace any conventional growing medium, whether natural or artificial.

The compounds of the invention may be used in a great number of crops, such as soybean, coffee, ornamentals (i.a. pelargonium, roses), vegetables (e.g. peas, cucumber, celery, tomato and bean plants), sugarbeet, sugarcane, cotton, flax, maize (corn), vineyards, pomes and stone fruits (e.g. apple, pears, prunes) and in cereals (e.g. wheat, oats, barley, rice).

The invention also provides fungicidal compositions, comprising as a fungicide a compound of formula I in association with an agriculturally acceptable diluent (hereinafter diluent). They are obtained in conventional manner, e.g. by mixing a compound of the invention with a diluent and optionally additional ingredients, such as surfactants.

The term diluent as used herein means liquid or solid agriculturally acceptable material, which may be added to the active agent to bring it into an easier or better applicable form, resp. to dilute the active agent to a usable or desirable strength of activity. Examples of such diluents are talc, kaolin, diatomaceous earth, xylene or water.

Especially formulations used in spray form, such as water dispersible concentrates or wettable powders, may contain surfactants such as wetting and dispersing agents, e.g. the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, an ethoxylated alkylphenol and an ethoxylated fatty alcohol.

In general, the formulations include from 1 to 90% by weight of active agent, from 0 to 20% agriculturally acceptable surfactant and from 10 to 99% diluent(s). Concentrated forms of composition, e.g. emulsion concentrates, contain in general from about 5 to 70%, preferably from between 10 and 50% by weight of active agent. Application forms of formulation contain in general from 1 ppm to 5000 ppm of a compound of the invention as active agent. Typical spray-suspensions may, for example, contain from 10 ppm to 1000 ppm, preferably from 50 ppm to 500 ppm, e.g. 100 ppm or 500 ppm of active agent.

In addition to the usual diluents and surfactants, the compositions of the invention may comprise further additives with special purposes, e.g. stabilisers, desactivators (for solid formulations or carriers with an active surface), agents for improving the adhesion to plants, corrosion inhibitors, anti-foaming agents and colorants. Moreover, further fungicides with similar or complementary fungicidal activity, e.g. sulphur, chlorothalonil, euparen; a guanidine fungicide such as guazatine; dithiocarbamates such as mancozeb, maneb, zineb, propineb; trichloromethane sulphenylphthalimides and analogues such as captan, captafol and folpet; benzimidazoles such as carbendazim, benomyl; azoles such as cyproconazole, flusilazole, flutriafol, hexaconazole, propiconazole, tebuconazole, epoxiconazole, prochloraz; morpholines such as fenpropimorph, fenpropidine, or other beneficially-acting materials, such as cymoxanil, oxadixyl, metalaxyl, or insecticides or acaricides may be present in the formulations.

Examples of plant fungicide formulations are as follows:

a. Wettable Powder Formulation

10 Parts of a compound of formula I are mixed and milled with 4 parts of synthetic fine silica, 3 parts of sodium lauryl sulphate, 7 parts of sodium lignin sulphonate and 66 parts of finely divided kaolin and 10 parts of diatomaceous earth until the mean particle size is about 5 micron. The resulting wettable powder is diluted with water before use to a spray liquor which may be applied by foliar spray as well as by root drench application.

b. Granules

Onto 94.5 parts by weight of quartz sand in a tumbler mixer are sprayed 0.5 parts by weight of a binder (non-ionic tenside) and the whole thoroughly mixed. 5 parts by weight of a compound of formula I of this invention are then added and thorough mixing continued to obtain a granulate formulation with a particle size in the range of from 0.3 to 0.7 mm (where required, the granules may be dried by the addition of 1 to 5% by weight of talcum). The granules may be applied by incorporation into the soil adjacent to the plants to be treated.

c. Emulsion Concentrate

10 Parts by weight of a compound of formula I are mixed with 10 parts by weight of an emulsifier and 80 parts by weight of xylene. The thus obtained concentrate is diluted with water to form an emulsion of the desired concentration, prior to application.

d. Seed Dressing

45 Parts of a compound of formula I are mixed with 1.5 parts of diamyl phenoldecaglycolether ethylene oxide adduct, 2 parts of spindle oil, 51 parts of fine talcum and 0.5 parts of colorant rhodanin B. The mixture is ground in a contraplex mill at 10,000 rpm until an average particle size of less than 20 microns is obtained.

Biological activity is determinated according to the following examples

Example A

Activity against Powdery Mildew

Sphaerotheca fuliginea:

Plants of Cucumis sativus (cucumber), 7 days old (cotyledon stage), are sprayed to near run off with a suspension containing 100 mg/l of active ingredient. The deposit is then allowed to dry. One day later, the treated plants are inoculated with a spore suspension containing 1×10⁵ /ml of freshly collected conidia of Sphaerotheca fuliginea and then incubated in the greenhouse for 7 days at +24° C. and 60% r.h.

The efficacy of the test compounds is determined by comparing the degree of fungal attack with that on untreated, similarly inoculated check plants. In this test compounds 1.03, 1.04, 1.11, 1.40, 2.04, 2.06, 3.02, 3.03, 3.04, 3.05, 3.06 and 3.13, showed an efficacy of more than 90%.

Similar methods are used to test the compounds against the following pathogens:

Podosphaera leucotricha on apple,

Erysiphe graminis on wheat and barley (dry inoculation),

Uncinula necator on grape.

Example B

Activity against Rust, Scab, Pyrenophora, Leptosphaeria

Uromyces appendiculatus:

Plants of Phaseolus vulgaris (pole bean), 14 days old (2 leaves stage), are sprayed to near run off with a suspension containing 100 mg/l of the active ingredient. The deposit is then allowed to dry. One day later, the treated plants are inoculated with a spore suspension containing 1×10⁵ /ml of freshly collected spores of Uromyces appendiculatus. Incubation is performed for 3 days in a high humidity cabinet at +23° C. and >95% r.h. and thereafter during 10 days at +24° C. and 60% r.h.

The efficacy the compounds is determined by comparing the degree of fungal attack with that on untreated, similarly inoculated check plants. In this test compounds 1.3, 1.11 and 1.40, 2.04, 2.06, 3.01, 3.02, 3.03, 3.04, 3.05, 3.06, 3.12, 3.13, 4.09 and 4.10 showed an efficacy of at least 90%.

Similar methods are used to test the compounds against the following pathogens:

Puccinia triticina on wheat (plants 10 days old),

Pyrenophora graminea on barley,

Leptosphaeria nodorum on wheat,

Venturia inaequalis on apple (plants 21 days old; the spore suspension contains 1% malt).

Example C

Activity against Downy Mildew

Plants of Lycopersicon esculentum (tomato) with 6 leaves, are sprayed to near run off with a spray suspension containing 500 mg/l of the active ingredient. The deposit is then allowed to dry. 1 day later, the treated plants are inoculated with a spore suspension containing 1×10⁵ /ml of freshly collected sporangia of Phytophthora infestans and then incubated for 7 days in a high humidity cabinet at +18° C. and >95% r.h. The efficacy of the test compounds is determined by comparing the degree of fungal attack with that on untreated, similarly inoculated check plants. In this test compounds 1.40 and 3.08 showed an efficacy of at least 90%.

A similar method is used to test the compounds against Plasmopara viticola on grape vine.

Example D

Activity after Seed Treatment

The compounds of the invention may also be used for seed treatment. The advantageous fungicidal activity is established by in vitro tests with the following pathogens:

Pyrenophora graminea,

Ustilago nuda,

Gerlachia nivalis,

Leptoshpaeria nodorum.

Autoclaved wheat seeds are inoculated with spores or mycelium of the pathogens and coated with different concentrations of the test compounds resulting in dosages of 50 g a.i./100 kg seed. The treated seeds are then placed on agar plates and the pathogens allowed to grow for 3-8 days at +24° C. in the dark.

The efficacy of the test compounds is determined by comparing the degree of fungal growth emerging from treated and untreated inoculated seeds.

To evaluate the crop plant tolerance of the compounds, healthy seeds of wheat and barley are coated with the dosages mentioned above. The seeds are then allowed to germinate in petri dishes on moist filter paper in high humidity at +18° C. for 10 days. Plant damage is recorded, comparing the growth of treated and untreated seedlings.

In this test compounds 1.41 showed an efficacy of at least 90% against Pyrenophora graminea.
